IMPLEMENT-CLAMP.

Speccation of Letters Patent.

Patented May 7, 1912.

Application filed February 8, 1910. Serial No. 542,797.

To all whom t may concern:

Be it known that I, SIMEON C. LAwLoR, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Implement-Clamps;A

and I do hereby declare the following to be a full, clear, andexactdescription ofthe 1nvention, such as will enable others skilled 1nthe art to which it appertains to make and use the same.

This invention relates to improvements 1n implement clamps, and theobject in view is the increasing of the utility and efficiency thereof.

lilith this and further objects in view as will in part become obviousandV in part be herein stated, the invention comprises certain novelconstructions, combinations and arrangements of parts as hereinafter setforth and claimed.

In the accompanying drawing,-Il`igur e 1 is perspective view of a clampembodying the features of the present invent-ion. Fig. Q is alongitudinal, vertical section therethrough taken on the plane indicatedby line 2, 2 of Fig. 1. Fig. 3 is a fragmentary, detail sectional viewillustrating a modified embodiment.

In the accompanying drawing, 1 indicates the handle which may be of theordinary type, and which is surrounded and engaged by the sleeve 2. Aclamping jaw 3 is carried by sleeve 2, and a complemental clamping jaw 4is pivoted to sleeve 2, as at 5, at the inner terminus of jaw 3. J aw 3is apertured, as at 6, for the passage of a clamping bolt 7 whichextends through a corresponding aperture in jaw 4 and is provided witht-he usual wing nut 8 below jaw 4, adapted to be manipulated for forcingjaw 4 into clamping relation with respect to jaw 3. The material of jaw3 has a small portion contiguous aperture 6 stamped outwardly,

.forminga lug 9, which, after bolt 7 has been positioned, is bent downover the head of the bolt for preventing the bolt from beingaccidentally detached from the clamp when nut 8 is removed.

The jaws 3 and 4 are, of course, adapted for grasping any implement, butto facilitate the grasping of a mop, or like device, I provide a claspwhich comprises a pair of rod aws 10, 10, pivotally connected togetherand having one IOd at each Side 0f Sleeve 2 projecting into the pivotopening of jaw 4,

the pivotal connection of jaws 10 being coaxial wit-h that of jaws 3 and4. The outer edge of each of jaws 3 and 4 is formed with a bent orturned portion 11 within the inner corner of which the cross rod of therespective jaw 10 lies, and said jaw may be retained therein by variousattaching means, but preferably by projecting tabs 12 extending from therespective jaw 3 or 4 and formed integral therewith and bent about thegiven rod. Obviously, the rod may be otherwise connected, as forinstance as seen in Fig. 3 wherein the rod is retained by rivets 13.

In clasping a brush or other like implement it is frequently desirableto cause the jaws 10 to grasp one portion of the implement and toutilize auxiliary means for grasping another portion thereof. As suchauxiliary clasping means I provide a hook 14, preferably formed of wire,with the free ends extending into and pivotally engaging a pair ofapertures 15 in the rear portion of jaw 3 or the front end of sleeve 2,A series of sets of apertures 15 is provided for allowing the hook 14 tobe adjusted along the aw 3 for accommodating various sizes of articlesto be clasped. Obviously, as many sets of apertures 15 may be providedand may extend as far along the socket or sleeve 2 as may be founduseful. Intermediate the length of hook 14 the wire arms which comprisethe hook are dellected or bent downwardly, as at 16, 16, for offering asupport for the hook when free from engagement with an implement, thuspreventing the hook from ever falling down in front of the clampingjaws. The outer ends of the arms comprising the hook 14 are spaced suchdistance apart as will allow them to spring past the sides of handle 1when the hook is swung to the dotted position seen in Fig. 2, said endswhen in such position clasping the handle sufficiently for retaining thehook in the out-of-the-way position.

Contiguous the pivots of the arms which extend from and carry theclasping mem. bers of clasp 10, saidarms are slidingly surrounded bygripping links or rings 17, 1 7, which are adapted to be shifted alongthe arms away from the pivot point for producing or retaining a grippingacti-on of clasp members 10, and for insuring a gripping action of theportions of the clasp outside the main clamp. Also, when it is founddesirable to omit bolt 7 to enable introducing the clamp in closequarters, the gripping rings 17 retain all clamping parts in grippingcondition, and may be causedto release the same merely by sliding therings 17 toward the pivots of the arms of clasp l0.

What I claim is l. In apparatus of the class combination with a pair ofpivotally connected clamping jaws of a pair of rod jaws secured to saidclamping jaws, respectively, along the clamping lines thereof, extendinglaterally beyond the same, and pivotally connected in the axial line ofthe clamping jaw pivot.

2. In apparatus of the class described, the combination with a pair ofco-acting clamping jaws, of a pair of broader rod jaws having theirclamping portions fixed to and substantially coinciding centrally withthe corresponding portions, respectively, of the clamping jaws, therearwardly and inwardly extending portions described, the

of one rod jaw forming two alining pivots for the compani-on jaw andsaid clamping jaws.

3. The combination with a handle member having a rigid projecting jawwith a broad clamping terminal margin, of a movable clamping jaw havinga. like and co-acting margin, a pair of broader rod aws each having itsterminal portion alining with and ixed to the corresponding portion ofone of said clamping jaws, one of the rod jaws having its ends passedthrough said movable jaw into said rigid jaw and the other pivotallyconnected to its companion at substantially its point of entrance intosaid movable jaw, and rings sliding, respectively, upon the adjacent,slightly divergent rearwardly extending portions of the two rod jaws,substantially as set forth.

In testimony whereof I aiix my signature in presence of two witnesses.
